Primary malignant bone tumours are a scarce entity with limited population-based data from developing countries. The aim of the study is to investigate the frequency and anatomical distribution of primary malignant bone tumours in a local South African population. This will be an epidemiological retrospective study. Data will be used of patients that were diagnosed with primary malignant bone tumours over a period of nine years spanning from 1 January 2014 to 31 December 2022. This data will be received from private and government laboratories. Data to be considered are type of primary malignant bone tumours diagnosed, incidence of primary malignant bone tumours over a period of nine years and the most common anatomical sites of primary malignant bone tumours. The rationale behind our study is to assess the frequency of different primary malignant bone tumours in another geographic area of South Africa and to compare these findings to local and international literature. With a projected increase in diagnosis of primary malignant bone tumours in developing countries it is important to have more available data about primary malignant bone tumours from these areas to have a better understanding of these conditions and to understand the impact of the burden they impose on healthcare systems so that management of these conditions can also be improved. Preliminary results show that 23.83% of primary malignant bone tumours occurred in the age group 0–24 years of age, 49.22% in the 25–59 age group and 26.95% in the 60+ age group. The most common tumour that occurred was chondrosarcoma (49.21%) followed by osteosarcoma (41.80%) then Ewing's sarcoma (4,69%) and lastly chordoma (4.30%). From the 256 samples that met the inclusion criteria the five most common anatomical sites were distal femur (63), proximal tibia (41), proximal humerus (38), pelvis (34) and proximal femur (20).
Distal radius fractures are common in South Africa. Accurate, decisive radiographic parameter interpretation is key in appropriate management. Digital radiographic facilities are rare in the public setting and goniometer usage is known to be low, thus, visual estimates are the primary form of radiographic assessment. Previous research associated orthopaedic experience with accuracy of distal radius fracture parameter estimation but, oftentimes, doctors treating orthopaedic patients are not experienced in orthopaedics. A cross-sectional questionnaire including four distal radius fracture radiographs administered to 149 orthopaedic doctors at three Johannesburg teaching hospitals. Participants grouped into ranks of: consultants (n=36), registrars (n=41), medical officers (n=20) and interns (n=52). Participants visually estimated values of distal radius fracture parameters, stated whether they would accept the position of the fractures and stated their percentage of routine usage of goniometers in real practice. The registrar group was most accurate in visually estimating radial height, whilst the interns were least accurate (p=0.0237). The consultant, registrar and medical officer groups were equally accurate in estimating radial inclination whilst the intern group was the least accurate (p<0.0001). The consultant and registrar group were equally accurate at estimating volar tilt, whilst the medical officer and intern groups were least accurate (p<0.0001). The Gwet's AC agreement was 0.1612 (p=0.047) for acceptance of position of the first radiograph, 0.8768 (p<0.0001) for the second, 0.8884 (p<0.0001) for the third and 0.8064 (p<0.0001) for the fourth. All groups showed no difference in goniometer usage, using them largely 0–25% of practice (p=0.1937). The study found that accuracy in visual estimations of distal radius fracture parameters was linked to orthopaedic experience but not linked to routine practice goniometer usage, which was minimal across all groups. Inter-rater agreement on acceptability of fracture position is potentially dependent on severity of deviation from acceptable parameters.
The musculoskeletal (MSK) profiles of water polo players and other overhead athletes has been shown to relate to injury and throwing performance (TP). There have been no robust studies conducted on the MSK profiles and the variables affecting TP amongst female, adolescent, elite water polo players. A prospective quantitative cohort design was conducted amongst eighty-three female adolescent, elite water polo players (range 14–19 years). All participants filled out the Kerlan-Jobe Orthopaedic Clinic questionnaire, followed by a battery of screening tests aimed to identify possible MSK factors affecting TP. Pain provocation tests, range of motion (ROM), upward scapula rotation (USR), strength and pectoralis minor length measurements were all included. Participants also performed throwing speed (TS) and throwing accuracy (TA) tests. All the data collected were grouped together and analysed using SPSS 28.0. The condition for statistical significance was set as p <0.05. Multi-collinearity was tested for among variables to find out inter-variable correlations. Finally, a multiple regression analysis was performed. The mean KJOC score was 82.55 ± 14.96. 26.5% tested positive for at least one of the impingement tests. The MSK profile revealed decreased internal rotation ROM, increased external rotation ROM, a downwardly rotated scapula, weak external rotators, weak serratus anterior strength, strong lower trapezius and gluteus medius strength and a shorter pectoralis minor length all on the dominant side. Age, pectoralis minor length, upper trapezius and serratus anterior strength as well as upward scapula rotation were all positively correlated with TS, while sitting height, upper trapezius and serratus anterior strength and glenohumeral internal rotation ROM were positively correlated with TA. Multiple MSK parameters were found to be related to TS and TA in elite, adolescent water polo players.
The Latarjet procedure is a well described method to stabilize anterior shoulder instability. There are concerns of high complication rates, one of these being a painful shoulder without instability due to screw irritation. The arthroscopic changes in the shoulder at time of screw removal compared to those pre-Latarjet have not been described in the literature. We conducted a retrospective review of arthroscopic videos between 2015 and 2022 of 17 patients at the time of their Latarjet screw removal and where available (n=13) compared them to arthroscopic findings at time of index Latarjet. Instability was an exclusion criterion. X-rays prior to screw removal were assessed independently by two observers blinded to patient details for lysis of the graft. Arthroscopic assessment of the anatomy and pathological changes were made by two shoulder surgeons via mutual consensus. An intraclass correlation coefficient (ICC) was analyzed as a measure for the inter-observer reliability for the radiographs. Our cohort had an average age of 21.5±7.7 years and an average period of 16.2±13.1 months between pre- and post-arthroscopy. At screw removal all patients had an inflamed subscapularis muscle with 88% associated musculotendinous tears and 59% had a pathological posterior labrum. Worsening in the condition of subscapularis muscle (93%), humeral (31%) and glenoid (31%) cartilage was found when compared to pre-Latarjet arthroscopes. Three failures of capsular repair were seen, two of these when only one anchor was used. X-ray review demonstrated 79% of patients had graft lysis. Excellent inter-rater reliability was observed with an ICC value of 0.82. Our results show a high rate of pathological change in the subscapularis muscle, glenoid labrum and articular cartilage in the stable but painful Latarjet. 79% of patients had graft lysis with prominent screws on X-ray.
The choice of whether to perform antegrade intramedullary nailing (IMN) or plate fixation (PF) poses a conundrum for the surgeon who must strike the balance between anatomical restoration while reducing elbow and shoulder functional impairment. Most humeral middle third shaft fractures are amenable to conservative management given the considerable acceptable deformity and anatomical compensation by patients. This study is concerned with the patient reported outcomes regarding shoulder and elbow function for IMN and PF respectively. A prospective cohort study following up all the cases treated surgically for middle third humeral fractures from 2016 to 2022 at a single centre. Telephonically an analogue pain score, an American Shoulder and Elbow Society (ASES) score for shoulder function and the Oxford Elbow score (OES) for elbow function were obtained. One hundred and three patients met the inclusion criteria. Twenty four patients participated in the study, fifteen had IMN (62.5%) and nine had PF (37.5%.). The shoulder function outcomes showed no statistical difference with an average ASES score of sixty-six for the IMN group and sixty-nine for the PF group. Women and employed individuals expressed greater functional impairment. Hand dominance has no impact on the scores of elbow and shoulder function post operatively. The impairment of abduction score post antegrade nailing was higher in the antegrade nailing group than the plated group. The OES demonstrated greater variance in elbow function in the PF group with the IMN group expressing greater elbow disfunction. This study confirms that treatment of middle third humerus shaft fractures by plate fixation is marginally superior to antegrade intramedullary nailing in preserving elbow function and abduction ability.
To employ a simple and fast method to evaluate those patients with neurological deficits and misplaced screws in relatively safe lumbosacral spine, and to determine if it is necessary to undertake revision surgery. A total of 316 patients were treated by fixation of lumbar and lumbosacral transpedicle screws at our institution from January 2011 to December 2012. We designed the criteria for post-operative revision scores of pedicle screw malpositioning (PRSPSM) in the lumbosacral canal. We recommend the revision of the misplaced pedicle screw in patients with PRSPSM = 5′ as early as possible. However, patients with PRSPSM < 5′ need to follow the next consecutive assessment procedures. A total of 15 patients were included according to at least three-stage follow-up.Objectives
Methods
To investigate the incidence of post-operative ulna nerve symptoms in total elbow arthroplasty after full in-situ release. A retrospective review was completed of the medical records of eighty-three consecutive primary total elbow arthroplasties (TEA) performed between 2003 and 2012. Data analysed included the presence of pre-operative ulnar nerve (UN) symptoms, history of prior UN transposition, intra-operative management of the UN and presence of post-operative symptoms.Aim:
Methods:
To investigate the clinical outcomes of elbows with post-traumatic stiffness treated by open surgical release. A retrospective review was completed on thirty-five consecutively managed patients who underwent an open elbow release for post-traumatic stiffness between 2007 and 2012. Pre-operative and post-operative range of motion (ROM), pain scores and functional outcomes were recorded.Aim:
Methods:
The primary treatment of congenital talipes equinus varus with the Ponsetti method remains the gold standard of treatment. Relapsed, neglected and/or teratogenic clubfeet pose a significant treatment challenge as the long term outcome of posteromedial release surgery is poor. Advances in circular fixation offer predictable deformity correction without the need for extensive soft tissue release. The Taylor Spatial Frame utilizes the correction principles of the “Ponsetti Method”, but little literature exists describing the correction of relapsed clubfeet with these fixators. This study assesses the outcome of relapsed clubfeet treated with the Taylor Spatial Frame Circular fixator. Ethics approval was obtained for a prospective descriptive study (N10-10-338). Patients with clubfeet who met inclusion criteria were treated with a Taylor Spatial Frame. The International Clubfoot Study Group Score was used to assess the feet preoperatively and six months postoperative. This scoring system scores the morphology, functionality and radiographic parameters of the clubfoot. Quality of life was assessed by means of the Child Health Questionnaire.Purpose of study
Methods
Comparison of the outcome between the supine or prone positioned child with a supracondylar humerus fracture by measuring anaesthetic and operating time, functional outcomes and complications. All children with isolated Gartland 2 and 3 supracondylar humerus fractures were who were admitted to our institute, were asked to participate in the the study. For surgery, the participating children were either operated on in a ‘supine’ or ‘prone’ position. The children were randomly allocated to either the ‘supine’ or ‘prone’ position. The fractures were preferably treated by closed reduction and percutaneous pinning with k-wires. However, if the fracture proved difficult to reduce, we proceeded to open reduction via medial and lateral approach. All fractures were stabilized with one medial and one lateral k-wire. The children were immobilized in a reinforced above elbow back-slab. Total anaesthetic and surgical time were meticulously recorded. Patients were followed up in our outpatient clinic at one week, four weeks (at which time the k-wires were removed). Three months post operatively, elbow extension, flexion and total range of movement was assessed in all children. Results Twenty children with isolated Gartland 2 and 3 supracondylar humerus fractures were included in this study. Nine children (5 ± 1 years, 7 boys and 2 girls) were operated on in a prone position, while 11 children (6 ± 2 years, 10 boys and 1 girls) were operated on in a supine position.Aims
Methods
To review the union rates, outcomes and complications of angular stable plating of lateral third clavicle fractures. Between 2007 and 2010 angular stable plates were used in the fixation for seventeen patients with displaced lateral third clavicle fractures (Allman Group II, Type 2). These were identified from surgical log books and operation codes. The surgical and clinical notes as well as X-rays were reviewed. The patients were contacted telephonically. An Oxford Shoulder Score and questions relating to plate removal, scar pain and return to activities were asked. Three patients were not contactable.Purpose:
Method:
We aimed to assess the short and medium term complications of patients who had undergone Latarjet procedures. We also compared this to a group of patients who over a similar period underwent an open Bankhart procedure to assess the complication profiles between the two groups. We retrospectively reviewed the notes and X-rays of all patients identified by surgical log books and or operation codes for instability. Eighty seven patients (88 shoulders) underwent Latarjet procedures between 2002 and 2010. Patients were phoned to obtain a telephonic Oxford shoulder score. There were 44 patients with 46 shoulders in the open Bankhart group.Purpose:
